IMPROVEMENT IN OUTHAUL BANDS FOR BOOMS.

Specification forming part of Letters Patent No. 121,890, dated December12, 1871.

To all whom it may concern:

Be it known that I, GEORGE NEVENGER, of the city and county ofPhiladelphia, inthe State of Pennsylvania, have invented a new anduseful Improvement in Outhaul Bands for Attaching Sails to Booms ofVessels; and I do hereby declare the following to be a full, clear, andexact description thereof, which will enable others skilled in the artto which it appertains to make and use the same, reference being had tothe accompanying drawing, which is a perspective View of my invention.

As now generally constructed outhaul bands are made in two parts hingedtogether, and must be opened when the sail is to be attached to the endof the boom or detached therefrom. This operation requires the man tohold the sail with one hand and the band with the other, and in roughweather it frequently happens that the band is dropped and lost.

My invention consists in an improved method of attaching the sail to theouthaul band, whereby the danger of dropping the latter is avoided.

A in the drawing represents part of the boom of a vessel, upon which isthe outhaul band B. This band is made with a lug, O. D is a clevis,through the eyes of which, as well as through the lug (J, passes thebolt E, provided with a slot and key, F. The sail is attached to theclevis in any convenient manner, as by cords passing through grommetsand a cleW, G.

In the operation of these devices, when the sail is to be attached tothe end of the boom the clevis is put through the clew or equivalent device and applied to the lug (J, the bolt pushed through the lug and theeyes of the clevis, and the Whole fastened by pushing the key throughthe slot. When the sail is to be detached the key and bolt arewithdrawn; and if from any cause the man should let go, the outhaulband, which remains fastened around the boom, will not be liable todrop, and the only thing lost will be the clevis, which can be easilyand cheaply replaced.

That I claim as my invention, and desire to secure by Letters Patent ofthe United States, is-

The combination, with the outhaul band B, of the clevis D, bolt and keyF, all constructed and operating as described.

GEORGE NEVENGER.
